Actually, as plenty of people have noted in the last page or two, there is plenty of factual evidence which shows that we do, in fact, work on multiple deals at once. There have been many signings, in the past few years even, announced within a day or week of each other.
Even if, for a moment, we ignore those facts, and assume that we are debating opinions, then it is my opinion that your opinion is ridiculous, utterly bizarre and not in any way credible. But alas, there are facts which support my view. So, whatever.
